REVIEW PERIPHERAL NERVOUS SYSTEM SOMATIC NERVOUS SYSTEM
AUTONOMIC NERVOUS SYSTEM SOMATIC NERVOUS SYSTEM MOTORIC NERVOUS SYSTEM SENSORIC NERVOUS SYSTEM NERVOUS SYSTEM CENTRAL NERVOUS SYSTEM PERIPHERAL NERVOUS SYSTEM AUTONOMIC NERVOUS SYSTEM PARASYMPATHIC SYMPATHIC
3
VISCERAL MOTORIC NEURON
DEFINISI Bagian dari SST Fungsi motorik Nervi craniales Nervi spinales Otot polos, otot jantung, glandula VISCERAL MOTORIC NEURON VISCERAL EFFECTOR
4
AUTONOMIC PATHWAY Memiliki 2 serabut neuron Preganglionik
SSP ganglion Postganglionik Ganglion efektor
5
THORACOLUMBAL DIVISION
SYMPATHETIC DIVISION THORACOLUMBAL DIVISION Menunjukkan asal neuron preganglionik bersinaps di ganglion dengan neuron postganglionik 1 preganglionik bersinaps dengan >>>> postganglionik KLINIS: jalur simpatik akan merangsang banyak organ sekaligus
6
TRUNCUS SYMPATHICUS
7
ILUSTRASI SIMPATIK pada keadaan stres akut Fight or flight
Stres akut teratasi ~ parasimpatik Terjadi efek sebaliknya
8
QUESTION ???? Simpatik >< parasimpatik Homeostasis
9
CRANIOSACRAL DIVISION
PARASYMPATHETIC DIVISION CRANIOSACRAL DIVISION Neuron preganglionik Medulla oblongata Mesencephalon Vertebrae sacrales Nn. craniales III, VII, IX, X Preganglionik ~ panjang Postganglionik ~ pendek
10
Nervi craniales
11
1 preganglionik bersinaps dg > 1 postganglionik
KLINIS: sebaran respon parasimpatis terbatas Umumnya organ menerima simpatik dan parasimpatik Beberapa organ HANYA SIMPATIK saja
13
Fungsi otonom
14
NEUROTRANSMITTER Komunikasi sinaps Preganglionik Asetilkolin (ACh)
ACh dari preganglionik didegradasi oleh kolinesterase di membran post sinaps Postganglionik Parasimpatik ACh Simpatik norepinephrin (NE) Inhibisi reuptake o/ membran presinaps
